elevators

Browse Source 
jump now applies the velocity of the block you jumped off of
  it might feel slightly different if you play n-gon often
  it could add some bugs so let me know

elevators have more realistic physics
  you can jump off them when they get to the top (fun!)
  blocks interact with them in a more healthy way (no bleed through)
  they can have a wider range of healthy speeds
  it can hurt mobs
